Mmmm that 26 pin analog connector, seems to be compatible with the one in my other JVS I/O which is a 837-14572.
I need to check my wheel, apparently something is wrong. It worked couple of days ago on Lindbergh but doesn't work now on Naomi?!?!
that's the type 3 i/o, it was designed for the lindbergh and newer sega JVS systems, but it's supposed to work on the older ones too. I don't have any experience with sega driving games so I can;t really help you out any further. I've emailed andy in the past, he's pretty helpful, give him shout !
